Different episodes of a series both have the cast & crew data of one of the episodes

There is an episode of a series with a certain cast, crew, and synopsis.  This same data has been mistakenly used for a second, different, episode, the cast, crew, and synopsis of which is unknown to me.  How do I remove the data from the erroneous episode?  I have a sneaking hunch IMDb isn't going to automatically accept a deletion of all the information for the erroneous episode, even though none of it applies to that episode.
